7204L50J

Overview

The Renesas Electronics Corporation 7204L50J is an asynchronous FIFO memory device belonging to the 7204 series. It features a storage capacity of 36K bits, organized as 4K words by 9 bits. The component operates with a maximum access time of 50ns and supports data rates up to 15MHz. It functions within a supply voltage range of 4.5V to 5.5V and utilizes a PLCC-32 package.

Feature Summary

• Asynchronous operation for independent read and write clock domains
• Uni-directional bus architecture
• CMOS technology implementation

Applications

• Data buffering in high-speed digital systems
• Interface bridging between disparate clock domains
• Temporary data storage in communication protocols

Procurement Notes

Verify current availability status as this component may be discontinued or subject to limited production runs. Confirm RoHS compliance requirements against specific project standards, noting that older variants may not meet current environmental directives. Validate package integrity upon receipt due to potential long-term storage conditions.

Selection Notes

Select this part when a 4Kx9 asynchronous FIFO with 50ns speed is required. Ensure system power supplies remain within the 4.5V to 5.5V range. Consider the PLCC-32 footprint during PCB layout. Verify if alternative pin-compatible devices are available if lead times are critical.

Part Context

This component is part of the broader 7204 family of asynchronous FIFOs from Renesas. It shares architectural similarities with other members like the 7204L25J and 7204L50P but differs in speed grade and package type. The 7204 series is designed for general-purpose memory buffering applications requiring simple interface control signals.

Replacement Considerations

Publicly confirmed substitute part numbers for the 7204L50J were not identified in the provided documentation. Cross-reference with IDT7204L50J if applicable, though verification of electrical compatibility is required.
